Gwynant is great. I was there for my first year. You will have a bit of noise around going out time at night, given that you are right next to the entrance to Ffriddeodd. But that is handy coming back from a night out, given you don't have to walk as far. If you are on floor four, three or two, you will have one of the best views over the valley on Ffridd. Just remember to dust every now and then. Also, don't pretend you're an elephant and stomp around the place, it will just piss people off.
